AUTOMATIC FLY-BRUSH.

SPECIFICATION forming part of Letters Patent No. 260,778, dated July 11, 1882.

Application filed April 27, 1882. (No model.)

'PEAY, and J. H. HELSLEY, of South Oarrollton, in the county of Muhlenburg and State of Kentucky, have invented certain new and useful Improvements in Automatic Fly- Brushes; and we do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a partof this specification.

Figure 1 is a side view of our improved flyfan, part of the box having been broken away in order to expose the operating mechanism. Fig. 2 is a side view, showing a modification; and Fig. 3 is a detail view of the crank-shaft I, Fig. 1.

Similar letters of reference, indicate corresponding parts.

This invention relates to automaticflyfans; and it consists in improvements in the construction of the same, which will be hereinafterfully described, andparticularly pointed out in the claims.

In the drawings hereto annexed, A represents a box or base, having bearings for a transverse shaft, B, driven by a spring, 0, from which motion is conveyed to said shaft in any suitable well-known manner, which may be, substantially as shown, by a train of gear- Wheels, D.

The box A is provided. with an upright, E, which may be tubular, so as to receive an extensible stem, F, which may be telescoped in the tube E or extended and retained in position by a set-screw, Gr.

The upright E is provided near its upper end with arms or brackets H, a short distance above which it has bearings for a transverse crank-shaft, I. The latter is provided at its front end with a crank wheel or disk, J, connected by a pitman, K, with a'crank-wheel, L, upon the front end of the shaft B. The

ends of the pitman K are curved, as shown, so that the dead-center shall be readily overcome.

M M are the fan-arms, which are pivoted to the outer ends of the brackets H, their upper ends being connected by pitmen N with the crank-shaft I.

O O are fiat springs attached to the lower ends of the arms M, and provided with light wire fingers P, to which the brushes Q, which may be made of paper, linen, or other suitable material, are secured, as shown.

The operation of our invention will be readily understood. The device may be placed upon the table, or wherever required, and the rod F extended until it touches the ceiling, thus bracing and. holding the device and preventing jostling. When the shaft B revolves a rocking motion is imparted to the crank-shaft I, which serves to oscillate the fans. The upper portions of the fan-arms, being rigid, are readily operated, while the elastic lower portions serve to make the motion of the brushes even and smooth. Fig. 2 of the drawings represents a modification of our invention. In this the box A is secured to the wallof aroom. The fan-arms M, with their springs O and brushes P Q, are pivoted in hangers R, suspended from the ceiling, and connected by the pitman K direct with the crank-wheel L upon shaftB. The operation is obvious.

Other motive powersuch as weights or a treadle-may be substituted for the spring herein shown without changing our invention. Having thus described our invention, we claim and desire to secure by Letters Patent of the United States-' 1.
